SPECIFICATION forming part of Letters Patent No. 537,109, dated April 9,1895. Appirettio filed August 29,1894.. serial' No: 521,638. (Nomodel.)Y

To otZZ whom t may concern:

Be it known that. we, SOLOMON M. HARRIS and MICHEL BREISOH, both of NewYork city, New York, have invented an Improved Window-Screen, of whichthe following is a specification.

This invention relates to a window screen which is adapted to vbeoperated by the sliding sashes, so as always to protect the openingsbelow or above such sashe's.

In the accompanying drawings, Figure l is an elevation, partly insection, of our iinproved window'screen. Fig. 2 is a longitudinalsection on line 2, 2, Fig. l; Fig. 3, a similar section, showingthe'sash b', in its lowermost position; Fig. 4, an enlarged verticalsection through the screens c, d, and Fig. 5 a detail of the fasteningdevices c.

The letter a, represents a window frame having a hollow lower box a2,and preferably a hollow upper boxe'.

21,5', are the upper and lower sliding sashes, of the usual or suitableconstruction.

To the lower railb2, of the lower sas/h b', there is adapted to besecured by catches c', the rigid frame of a window screen c. This screenis provided with grooves c2,in its side rails, adapted to be permanentlyengaged by pins d', of a second screen d. When the sash b', is lowered,both the screens c, d, are lowered into the hollow box a2, through aslot a3 (Fig. 3); but when the sash b', is raised, the screenc, will bedrawn up with it, to close the space beneath such sash. If the sash b',

is raised still farther, the screen c, will by pins d', and grooves c2,raise up the screen d, and in this way the entire open space beneath thesash may be protected by the screens (Fig. 2). Y

The object of making the screen in two parts is to permit it to bereceived within a comparatively shortbox a2, of the frame a.

VThe topv rail-c3, of screenVc, should have a beveled rear edge, toengage a packing strip c4, of slotcts, so as to closeA said slot againstthe weather when the screen is lowered.

Upon thetop rail h3,of upper sash Z),is supported latop screen e, whichrests upon 'the sash by its own gravity and is raised and lowered withthe same. The frame ct, should, of course, be provided with a slot a4,at the lower end of box a', to permit the screen e,

to be slid into such box. What we claim is A window frar'ne having a boxin its lower portion, and the lower sash, having engaging hooks fastenedto its lower edge, combined with the two vertically moving screens, oneof which is provided with pins with which the hooks engage, and groovesin its side rails, and the other having pins which catch in the grooves,whereby when the lower sash is closed it engages with one of thescreens, and when raised it successively raises both of the screens,substantially as shown.
